L2x2x1/8 — Dimensions, Weight & Section Properties
Steel angle (L-shape) per ASTM A6 / AISC Steel Construction Manual
L2x2x1/8 is a hot-rolled steel angle with equal 2 in (50.8 mm) legs, 0.125 in thick, weighing 1.65 pounds per foot (2.5 kg/m). All values below are the standard AISC published section properties, with metric equivalents alongside.
Typical uses: bracing, lintels, shelf supports, frames, and connection material. Angles are weak about their minor axis — long unbraced angles need lateral restraint. For a quick check, see the deflection example below or open the beam calculator.

Deflection example
A simply supported L2x2x1/8 spanning 3 ft with a 10 kip point load at midspan deflects 1.76 in (E = 29,000 ksi, Ix = 0.19 in⁴). The L/360 serviceability limit for this span is 0.1 in — the shape does NOT pass this quick check.

Frequently asked questions
How much does a L2x2x1/8 angle weigh?
L2x2x1/8 weighs 1.65 pounds per foot (2.5 kg/m). A 20 ft bar weighs 33 lb and a 40 ft bar 66 lb.
What are the dimensions of a L2x2x1/8?
L2x2x1/8 has two equal 2 in (50.8 mm) legs, both 0.125 in thick. Angle legs are measured outside-to-outside, and both legs share the same thickness.
What are the dimensions of a L2x2x1/8 in mm?
L2x2x1/8 has two equal 50.8 mm legs, 3.2 mm thick. In metric section properties: Ix = 8 cm⁴, Sx = 2 cm³.
How much does a L2x2x1/8 weigh in kg?
2.5 kg per meter. A 6 m bar weighs 15 kg and a 12 m bar 29 kg — handy when ordering US shapes from metric suppliers.
What is the moment of inertia of a L2x2x1/8?
About the strong axis, Ix = 0.19 in⁴ (8 cm⁴) with section modulus Sx = 0.13 in³. About the weak axis, Iy = 0.19 in⁴ and Sy = 0.13 in³. Use the beam deflection calculator to turn these into deflection and stress for your span and load.
L2x2x1/8 or L2x2x3/16 — what does one size up change?
L2x2x3/16 is about 48% heavier (2.44 vs 1.65 lb/ft) but about 43% stiffer (Ix 0.27 vs 0.19 in⁴). Going one step up within the same depth group is usually the cheapest way to cut deflection.
